Like the title says. Can I run open downpipe? I have a TBE with testpipe. The gasket between the downpipe and testpipe blew. I'm having trouble finding another gasket at local auto stores so. In the mean time, can I leave the downpipe/testpipe unbolted and drive around like that until I get another gasket?
Thanks

 

You can but it'll probably stink a lot since the exhaust fumes are right underneath you and it'll probably be very loud.

 

Of course, GO FOR IT!!!

Just dont make a thread about how cops are always harassing you

 

DOOO EEEETTTTT!!!!

lol i ran open downpipe for ONE DAY, was going to the track on the weekend. I had t he exhaust bolted off to the side. I ended put putting my exhaust back on because it was so lound and everything in the car was rattling.

 

If you have the rear o2 plugged into the test pipe or the anti-fouler you won't throw a CEL.

I ran minus the entire exhaust... because I had the wrong bolts for my downpipe. Didn't realize the thread was different and wound up stripping it and had to wait to get the right ones. It sounds very... ehh... lawnmower/honda'ish.

 

You can but it will be loud, smelly, and you may shoot a couple of flames under the car

 

Its all good baby.

youll sound just like the cavelier that reved me at a stop light while opening his cut out to 'SCARE"me ooooohhhhhhh.

 

love the way the evo sounds with open downpipe!!!

 

go for it! yes it will be loud and yes everyone will think your all noise and no go.

bbbuuttt its one of the best ways to spool a turbo faster!!

dooooooooooooit

 

there's actually a video of someone running an open downpipe on youtube I think... it was loud and obnoxious...

 

more power! I did that with me h22 prelude. loud as hell. turbo sounds cool though. seeing how it's an Evo, you might throw some sweet flames out the pipe....mainly set your car on fire. It would look sweet though. j/k..let it rip man!

 

there was someone on here with a cut out awhile ago. it was a stock turbo'ed motor and he said it dramatically reduced spool times, and made more power!

with a cutout you could run it nice and wuiet on the street, then open it up when you need it.

Chris.

 

yes

 

Koo. It's not like i wanna do it on purpose. hehe Maybe I can sound like a riced out evo and have more people pick on me thinkin i'm slow. Is there a place online where I can go to get a 3 inch 2 bolt exhaust gasket?
